CONVERTER FOR METAL.

Specification of Letters Patent.

Patented An": 13, 1912.

Application filed September 23, 1907. Serial No. 394,074.

T 0 all whom it may concern:

Be it known that I, ALEXANDER ZENZES, a subject of the Emperor of Germany, residing at Berlin, Germany, have invented certain new and useful Improvements in Converters for Metal, of which the following is a specification.

This invention relates to converters and has for its objects; the provision of an improved form of converter wherein the shell or body portion may be easily and conveniently removed from the rest of the apparatus for replacement and repair.

One embodiment of the invention is illustrated in the accompanying drawing, wherein Figure 1 is a front elevation of the con verter, Fig. 2 is a side elevation of the converter, Fig. 3 is a longitudinal section through the converter, Fig. 4c is a transverse section through the construction shown in Fig. 3 on the line IV-IV, Fig. 5 is a partial section through the construction shown in Fig. 3 on the line VV, and Fig. (3 is a partial section illustrating a modified arrangement of air box and twyers.

In converters heretofore constructed the shells or body portions have been made with the air box and trunnions permanently secured thereto, and the relining and the repair of the shell has been a ditlicult and long drawn out procedure as the heavy trunnions and air box made the shell diflicult of removal and during the repair thereof the whole apparatus was necessarily idle. My invention is designed to improve these conditions by providing a shell or body portion detachable from the air box and trunnions. By this arrangement the shell is very much reduced in weight so that it may be easily removed, and the air box and trunnions still remain in service. By keeping a number of shells on hand, the apparatus may be kept practically in continuous service as an injured shell may immediately be replaced by a new one.

Referring to the drawing, 1 is the body or shell of the converter which is of sheet metal and is lined with refractory material 2, 3 is the support for the device, 4 is the air box which encircles the body of the converter and is provided with the trunnions 5 pivoted in the support 3, and 6 is a clown- Wardly extending connection from the air box 4, whereby the air is conducted into the twyers 7 (Fig. 5). As shown in Figs. 3 and 5, the body or shell is provided with a plate 7 having openings 7 in register with the twyer openings 7, the connection 6 being flanged, the peripheral contour of the flanges and plate 7 substantially corresponding. \Vhen the shell is in position the flanges will contact with the face of the plate 7, the parts being so arranged as to substantially prevent the escape of air from the connection (3 excepting through the twyer openings. When the connection (3 and plate 7 are properly positioned with respect to each other, bolts (5 are inserted through the flanges, into the converter shell, said bolts tending to draw the connection and plate into close or mating contact. The body or shell 1 is supported in the air box 1 by means of the encircling angle iron ring 8, which is rigidly secured to the shell 1 and rests upon the top of the air box Al. The member 8 is secured to the air box by means of the removable studs or bolts 9 (Fig. at) as illustrated most clearly in Fig. 4. The trunnions 5 are hollow for the admission of air to the air box 4-, and one of such trunnions is open for connection with some source of air supply, while the other one is closed by means of the plug 10. The right hand side of the air box is open, and for this side a cover 11 is provided, which cover is made of very heavy metal and serves as a counter-weight for the converter. The converter is tilted by the usual gear 12, and other coiiperating gears not shown. The right hand end of the member 6 is removably bolted to the side of the converter, and when these bolts (3 are removed, and the bolts 9 to the ring 8, the shell is free to be lifted out of the air box t. It will be seen that by this arrangement the converter shell or body may be easily removed for repair, and that its place may be taken by another converter body, so that no time need be lost during the repair of the first converter body.

In Fig. 6, a somewhat modified form of apparatus for introducing the air into the converter is shown. In this arrangement each of the openings 7 is provided with a twyer 13. Each of these twyers 13 is governed by a rotating valve 15 having ports 14: whereby the twyers may be cleaned. The twyers 13 are supplied from the air box 4; by means of a plurality of vertical branch support, an annular air box provided with trunnions pivoted in the support,-one of said trunnions being hollow for the admission of air, a converter shell or body having an air inlet port opening inwardly and positioned below the plane of the air box when the parts are assembled, means for connecting the air box to-the air inlet port of the shell, said shell or body provided with supporting means abovethe air inlet and adapted to cooperate with said air box to position the shell or body, the lower end of the shell being of a diameter to pass through the air box until the supporting means has seated, and means for securing the supporting means to the upper surface of the box.

2. In a converter, the combination of a support, an annular air box provided with trunnions pivoted in the support, one of said trunnions being hollow for the admission of air, a converter shell or body having an air inlet opening inwardly and positioned below the plane ofthe air box when the parts are assembled, means for connecting the air box to the air inlet port-of the shell, said shell or body being provided with supporting means above the air inlet and adapted to cooperate with said air box to position the shell or body, the lower end of the shell being of a diameter to pass through the air box until the supporting means has seated,

and means for securing the supportingmeans to the upper surface of the box, said air box and trunnions consisting of one integral casting.

3. In converters, the combination with a vessel support provided with an air blast connection permanent therewith and having an air blast port opening inwardly, of a removable converter vessel provided with an 4:- In converters, the combination with a -vessel support having an air blast connection permanent therewith, an air blast port leading therefrom. and a face around the port, of a removable converter vessel provided w-ith an air blast port and a face around. the

same adapted to be forced into mating air tight register with aforesaid face of said air blast port when the vessel is inserted in the support.

5. In converters, the combination with a vessel support provided with a permanentlyattached air box and an air blast opening inwardly leading therefrom, of a removable.

converter vessel provided with an air inlet opening adapted to register with said air blast opening when the vessel is inserted in the support, and means for forcing said openings into register and maintaining a mating air-tight fit between them.

6. In converters, the combination with a removable converter vessel provided with an air inlet opening in its side wall, of a vessel support adapted to encircle the vessel and provided with an air blast connection permanently attached thereto, and an inwardly extending air blast passage communicating with said air blast connection, said support being adapted to carry said vessel andmaintain said air openings in air-tight register.

7. In a converter, the combination of a vessel support provided wit-h an air passage, an air box communicating therewith having an inner face provided with an air out-let, a removable converter vessel having twyers entering through the side into the vessel chamber and having an inlet plate corresponding in contour to the inner face of the air box and having a port communicating with the twyers, and means for forcing the inlet plate into contact with the air box.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
